Parabolic and they use it because light hits your face (the focal point) and gets reflected in the mirror. The concave, or parabolic, shape of the mirror surface concentrates the light beams, intensifying light as it gets closer to the focal point! :)

Answer:
Explanation:
m / z = 20 , 21 , 22
m / 1 = 20 , 21 , 22
m = 20 , 21 , 22 .
ratio of isotopes = 112 : 0.21 : 11.1
Average atomic mass = (112 x 20 + .21 x 21 + 11.1 x 22) / (112 + .21 + 11.1 )
= (2240 + 4.41 + 244.2) / 123.31
= 2488.61 / 123.31
= 20.18
Carbon dioxide = CO2
.5 mol CO2 = 1 mol O
1 mol O = <span><u>6.022140857 × 10^23 Oxygen atoms</u></span>
